The simple marine animals called corals inhabit the Great Barrier Reef for more than a thousand years. 3,000 is the number of individual coral reefs, plus 300 small coral islands, forming the largest structure in the world, composed of living organisms.

As is known, are marine coral formations and can not grow above the surface of the sea level as the bad weather conditions the air and rain, or other underwater currents may even kill them. Coral reefs do not grow deeper than 150 meters because they require the presence of sunlight to survive. Some areas of the Great Barrier Reef began to grow before over 2 million years, but a significant part of them develop nearly 500,000 years. The period of active growth starts before about 8,000 years ago and was interrupted by the global changes in sea level and temperatures in the Ice Age. At that time, melting glaciers caused the growth of the sea level, flooding continental shelves and forming shoals, especially useful for the growth of coral
About 1,500 species of fish may be found around them. The seahorse is one of the most colorful coral creatures. The Great Barrier Reef is of paramount importance for the life and reproduction of thousands of marine life. This includes and those animals and plants that live outside water. Such are the many species of birds nesting on the islands, as well as turtles and many others. Turtles spend their lives in the water, but lay their eggs on the beach. Eggs are heated below the surface of the sand and so develop a new generation of turtles. But for that we need a deserted beach, where people don't come. This is an important number of visitors in the area of the reef to be monitored carefully and not exceeds certain standards.To preserve the local environment by mass tourism,people control the upcoming tourists. So that the damage of tourism on the environment is minimized, but the seeking for tourism products is increasing. Tourism linked to the richness of reefs is a huge industry that favors solid economy of Queensland. The Great Barrier Reef is visited by nearly 1.6 million tourists each year. Thousands of tourists annually visit the Great Barrier Reef, to scuba diving, enjoy spectacular sea paintings and generally to enjoy this wonderful sea of uninhabited from people area. Many environmentalists, however, are worried about the massive presence of people here and they want it to be limited. This
